Y osClLLATlNe BED-SPRING.

SPECIFICATION forming part of Letters Patent No. 357,215, datedebruary 8, 1887.

Application filed June 29, 1886.

To all whom it mag/concern:

Be it known that I, J osIAE: B. MASTERS, a citizen of the United States, residing at Johnsonville, in the county of Rensselaer and State 0f New York, have invented a new and usefulV yvention more particularly relates to that class of spring-frames which are shown and described in my former patent, No. 257,879, dated May 16, 1882.

The object .of the invention is to cheapen and strengthen the construction of this class of devices and to avoid the defects incident to the use of wood employed in the device referred to as embraced in my said patent.

To the above purposes my invention consists in certain peculiar and novel features of construction and arrangement, as hereinafter describedand claimed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure 1 is a plan View of my improved spring-frame applied to a bedstead. Fig. 2 1s a longitudinal vertical section of the same on the line rc a: -of Fig. l. Fig. 3 is a transverse vertical section of the same on the line y y of Flg. l. Fig. 4 illustrates certain details of construction, hereinafter referred to. e

A designates the springs or spring-slats forming the bodygof the device, and B B designate the end bars, to which said springs are connected, in the` manner hereinafter described. Each of these end bars, B, is composed of a central tubular section, b, which is to be of varying lengths, according to the width or size of bedsteads to which the device is to be applied.

. C C designate longitudinal arms, which are coupled to the ends of the centraltubular sec- Beyond these tubular T-sections c extend tubular sections b', forming continuations of the end bars. It will thus be seen that the end bars are tubular throughout, and that they may be made of greater or less length, as desired. Each pair of arms C are connected at their rear ends by on the inner faces of the end bars.

Serial No. 206,634. (No model.)

a cross-bar, D, and said arms C extend upward above the level of the end bars, B, at their outer ends, so that the cross-bars D lie above the level of said end bars and strain upward upon thesprings A. To each end of each of the end bars,B,is inserted an extension,E, carrying upon its outer end the bracket F similar to that described in my former patent, No. 257,879, and the portion of the extension within the end bars is impinged upon by a setscrew, e, in such manner as to hold the extension at any desired point of adjustment within the end bar. It will thus be seen that these extensions serve to further extend the end bars, and also to more readily contract their length than could be done by removing the sections b.

Ratchet-plates G are secured upon the inner sides of the bedstead-frame, and the teeth of said ratchet-frame are engaged by an arm, g, in the manner described in my said former patent. The ends of the springs A are bent under and over the end bars, B, and their extremities are turned in upon slots b2, formed Thus no pins or bolts are required to fasten the springs to the end bars, and the springs are more readily attached to and removed from Said end bars than would otherwise be the case.

The operation of thisfstructure is essentially the same as that described in my former patent, previously alluded to. Then the brackets are set lower down upon the ratchet-plates, the springs are strained and th'e bottom of the `bed is made more rigid than when the brackets are adj usted to the upper part of the ratchetplate, and consequently the sustaining-power of the bed-bottom may be readily varied to suit heavier or lighter persons.

In lieu of the brackets F, the ends of the eX- tensions E may be provided with T-shaped heads, by which the spring-frame is suspended from the bedstead-frame, in which case the ratchet-plates may be dispensed with.

Having thus described my invention, I claim- 1. The herein-described improved bed-bot tom, consisting of the extensible end bars, B, having the arms C and cross-bars D, and the springs A, connected to the said end bars, sub- Stantially as described.

2. The combination, with the tubular ex- IOO tensible end bars, the longitudinal arms, and the cross-bars, of the springs A, suitably connected to said tubular end bars, and thc extensions E, and means for connecting said extensions Witll the bedstead-frame,substantial] y as described.

3. The combination, with the tubular end bars, composed of the central section, b, T- sections c, and tubular extension b', of the springs A, having their ends inserted in the slots in said cud bars, the longitudinal arms C, connecting` the cross-bars D and inserted into the T-scctions c, and suitable means for connecting the springbottom with the bedstead-frame, substantially as described.

4L. The combination, with the tubular extensible end bars and the extensions E, of the ratchet-plates connected to the bedstcad-frame, the arms C, andthe cross-bars D, substantially as described.

In testimony that I claim theforcgoing as my own I have hereto affixed my signature in presence of two witnesses.
